Here in NJ we haven't adopted the 2008 NEC yet. It is coming up for adoption I think in April. I am telling all the EC's here in NJ to flood the state website and demand that the state strikes the tamper proof receptacles from our code. It looks like the manufactures are just trying to push their products down our throats again. It think it is very wrong, and don't think or aging seniors will be able to deal with the new tamper proof plugs. (What if you have a 2 prong radio? Will it open some of the tamper proof types of receptacles?) I will now get off my soap box.
